Pete Seeger, the great American folk singer who turns 90 next week, sits down here with biographer Alec Wilkinson, and talks about Turn! Turn! Turn!. It’s a song that Seeger wrote in 1959, using lyrics taken from the Book of Ecclesiastes in the Bible. And it was then famously covered by The Byrds in 1965 (watch a performance here) and that version lives on today. To see Seeger performing this tune, click here. This one is for you Bob!
